Title: Water proof work execution method
Inventor: GUNJI SATORU
IPC: E04G21/02
Filed: 1989-10-04
Abstract: PURPOSE:To shorten construction period by spreading a permeable hydrophobic sheet,which lets steam pass and intercepts water, on cement ground, and making a waterproof layer after curing of the ground. CONSTITUTION:A porous hydrophobic sheet 2 consisting of porous polytetafluoroethylene, or the like, which lets steam pass but does not let water pass, is provided. Next, ground 1 such as mortal, cement, etc., is placed, and thereon a sheet 2 is layed, and is cured and hardened. Next, the sheet 2 is exfoliated, and a waterproof sheet 3, where an air escaping groove 33 is made, is bonded to the ground 1. Moreover, in case of executing waterproofing with the sheet 2 stuck to the ground 1, an adhesive, which has some solidity, is applied partially so as to bond the ground 1 with the sheet 2, and after curing, the waterproof sheet 3 is bonded. Hereby, the work can be done in the same construction period and quality as the case where it does not rain, and besides the sheet 2 can also substantially contribute to waterproofing.

Patent JP-S63114605-A (JP)
Title: Warmer
Inventor: SATO NORIMOTO
IPC: B29B13/02
Filed: 1986-10-31
Abstract: PURPOSE:To enhance the efficiency of warming operation by a method wherein plastic material is spirally shifted by being spirally wound round the periphery of a roller so as to shift it axially from one end side of the roller to the other end side in order to take it out of the other end side of the roller. CONSTITUTION:Cooled and hardened rubber G is supplied in the wide width side inlet 5a of a wedge-shaped space 5 at the one axial end side of a roller 4 by means of a conveyer 21. Because the irregularities are provided on the outer periphery of the roller 4 at the one axial end side, the irregularities bite in the rubber G, thereby forcibly pulling the rubber G in a wedge-shaped space 5. Since the rubber G is low in temperature and consequently does not be allowed to deform by flowing plastically, the rubber G is compressed from both sides by an arcuate surface 3 and the roller 4, resulting in being cracked internally or crushed into small pieces and slightly raising the temperature through kneading. The rubber G is spirally shifted round the roller to the other axial end of the roller 4. The rubber G is warmed up with every one turn round the roller 4 by passing through the wedge-shaped space 5. Since the wedge- shaped space 5 is formed between the recessed arcuate surface 3 and the projecting surface of the roller 4, the space 5 can be extended over a long distance, resulting in enhancing the warming-up effect.

Title: Operation monitoring device for electronic equipment
Inventor: IBUKI TSUNEJI
IPC: G01R31/06
Filed: 1986-10-31
Abstract: PURPOSE:To detect abnormality of a breaker even if an electromagnetic coil is broken by dividing the terminal voltage across the electromagnetic coil and measuring the operation time of electric equipment from the voltage division output. CONSTITUTION:A breaking mechanism which is not shown in a figure is operated through the lead-out coil 1 of the breaker 1 and a switch 2 is opened to cut off electric feeding to the coil 1. The terminal voltage across the coil 1 is divided to develop a voltage proportional to the coil voltage across a resistance 6b, and the voltage is inputted to a decision means 4. The output of a comparator 8 is supplied to a timer 9, whose pulse time width is measured. This pulse time width is monitored by a decision device 10 to judge whether the breaker is normal or not. Then if the coil 1 is broken, a voltage is developed across the coil 1, but the breaking mechanism does not operate, so the switch 2 is not opened. The pulse time width measured by the timer 9, therefore, increases abnormally, so the fault of the breaker is detected from the time width of the pulse even if the coil is broken.
